PT4107 Universal High Brightness LED Driver

The PT4107 is a high voltage buck control IC for constant LED current regulation. It allows efficient operation of High Brightness (HB) LEDs from voltage sources ranging from 18VDC up to 450VDC or 110VAC/220VAC. The PT4107 controls an external MOSFET at fixed switching frequency from 25 kHZ to 200 k.
